Over 14m USD was paid for the most expensive book at the moment (at New York’s Sotheby’s) which is Bay Psalm Book which was published in 1640. Only 1700 copies of the psalm book were published by settlers in Cambridge, Massachusetts and currently there are only 11 copies in existence. The book has 300 pages. Only manuscripts and hand written books were more expensive. In 1994, Leicester Codex (writings and notes made by Leonarda Da Vinci in XVI century) fetched 30.8m USD.
